Apparatus and method are provided for teaching and/or improving upon the mechanics of the whip kick that may be used while performing the breaststroke and training the competitive breaststroker. The tool includes a fin that is configured toreceive a swimmer's foot and a propulsive blade that engages the water at the beginning of the propulsive phase of the kick, such as when the swimmer's legs have reached maximum flexion at the knees, with feet positioned slightly wider than the knees, heels turned in while the toes are turned out and ankles flexed. As the swimmer initiates the power phase of the kick, the propulsive blade achieves maximum purchase of the water. As execution of the power phase continues, the propulsive blade channels the captured water backward and away from the swimmer, remaining stiff enough to hold onto the water while force is applied, yet sufficiently flexible enough to recover or flip downward as the swimmer extends the ankles and rolls the outer edges of his/her feet over and inward, snapping the soles together. |
